| QC1PARAM |
QC1 parameters written into QC1 database: QC1 DB names: darklevel_ft | darklevel_sc | darkrms_ft | darkrms_sc | biasavg_sc | biasrms_sc | numpix_zero_acq All parameters (except numpix_zero_acq) are calculated by the pipeline recipe. | ||||||||||||||||||||||||||||
| ALGORITHM |
Description of algorithms: darklevel_ft: The master is determined as the median stack of the input data; the QC parameter is the average of the all pixel values in the master. darklevel_sc: The master is determined as the median stack of the input data after bias subtraction; the QC parameter is the median of the all pixel values in the master. darkrms_ft: Standard deviation of FT master dark. darkrms_sc: Standard deviation of SC master dark. biasavg_sc: The average bias that is subtracted from each input frame in case of the SC detector. The actual dark level of the input frames is then darklevel_sc + biasavg_sc. biasrms_sc: The standard deviation of the individual bias values per input frame. numpix_zero_acq: The number of pixels of the acquisition camera that have 0 ADU. | ||||||||||||||||||||||||||||
| CERTIF |
Reasons for rejection: unusual dark level or read-out noise, change of structure | ||||||||||||||||||||||||||||
